yup same here (2019 Trailboss) tires rotated every 5k. at 20k miles the noise was unbearable at 55mph, my wife wouldnt even ride in the truck anymore. Rebalanced the tires and it was ok till the next rotation. now up to 36k with another rebalance and I cant even take it anymore. tires are probably 40% treadlife left. outsides and insides are scalloped. its happening when they are on the front. when they are on the rear you can see that the worn areas are not touching the road, but the front have full contact. BFG T/A KO2's are coming shortly. i will most likely do shocks at the same time.

I had a 2019 LT Z71 as a loner with the smaller Infotainment screen than my truck and the phone volume was fine via Bluetooth. I had my phone on vibrate at the time as well.

They replaced the oil cooler lines, refilled oil, changed filter on mine. I had expressed my concern over a possible fatal issue. I allowed the Service Manager to take my truck home overnight to put some miles on it (~90miles). There was no unusual sounds after so I took it home. I have put another 500 miles on it without any issue. They said about 2 quarts of oil was left and they allowed me to keep the oil filter, which I will cut open (reality is that probably didn't collect any oil anyway as it all went on the ground and didn't recirculate). I pulled a small sample (4 ounces)of oil out when I got home and I do not see any flakes, particles, or shiny stuff. Pretty crazy that I had almost 8,000miles on it when it went. I figured something like this would happen early on, or during the winter at a -10degree start. i will probably take another oil sample this weekend and maybe switch out the oil filter again to check that one. I had my truck shut off pretty quick, so that may be why I escaped major damage. With another 50k miles to go on the powertrain warranty I think any issue will show up before then.. My Truck was built in Ft. Wayne 140xxx serial number. I picked it up just after Thanksgiving 2018.

i have this issue too. only on Bluetooth. If i have it plugged in it is super loud. My phone is normally on vibrate, so I will pay attention if it changes when I have the ringer on. I have iOS 12.1.2 and this has been this way since November when I first got the Truck. I have done 3 Infotainment Software updates so far.

This Just Happened to me on the way home from work on Monday. 2019 LT TrailBoss, 7552miles. They are replacing the hoses currently. Waiting on the part to be delivered today. what a mess on the road and the whole underneath of the truck! They dont seem to be worried about the engine running without oil, although I am. Thankfully I had it off the road and turned off within 30seconds. I did not hear any funny noises. I will be pushing for oil analysis, oil usage tracking and i will want some sort of good faith for engine longevity.
